RHESSI
made 6 passes per day of 9.2 minutes average duration over the primary ground
station located at UC Berkeley. An average data volume of 11
Gbytes/day were downlinked at a rate of 4 MBytes/day. The ground
station at UCB was used for primary command and data reception. The
Mission Operations Center (MOC) at UCB operated the spacecraft and
instrument.

The
RHESSI data were sent to UCB's Science Operations Center (SOC). At the SOC, the data was
catalogued, archived, and cut onto CD-ROMs. The CD-ROMs were then
distributed to co-investigators, Solar Data Analysis Center at Goddard Space
Flight Center, High Energy Data Center at ETH in Zurich, and of course, the
local archive at UC Berkeley. From the local archive, the RHESSI
data was distributed to the world-wide web. The SDAC archived
and distributed both data analysis software to outside users in the U.S. and
provided contextual observations from other spacecraft and ground
instruments. The HEDC performed the same function in Europe.
